Description

Sample available here: http://www.eactothegame.it/prove/sample3.mov That sample plays without problems in vlc and mplayer, I think it's caused by some b-frame options like b-pyramids, but I'm not sure.

Since you said h.264, I must assume you mean svn. What version?

Reproducable for me in r289, and there haven't been any related changes since then.

I guess we're ignoring some of the many bframe-related atoms in this?

Do we need to block 1.1 on this?

I think we should blame x264qtcodec for this, if b-pyramid is enabled, it still flag all b-frame as "droppable", and then quicktime goes crazy. But I am not an expert, so I may be wrong.

If the atoms say it's skippable I'm not sure we can do anything.

  • milestone changed from 1.1 to Sometime after 1.0.

We're not blocking 1.1 on this.
